             abstract = "Sea turtle movements are influenced and driven by marine currents. 
                         Their occurrence is determined by prey availability and sea 
                         temperature, with an apparent spatial association with frontal 
                         systems. Caretta caretta movements in the Western South Atlantic 
                         present seasonal patterns according to variability of sea surface 
                         temperature (SST). We analyzed daily SST data and correlated it 
                         with telemetry position of seven loggerheads incidentally captured 
                         in pair trawl fisheries, between March 2013 and October 2014. To 
                         validate SST data from the OSTIA system, we compared them with SST 
                         from telemetry data. Results showed a high correlation between 
                         measurements (r=0.88) and absolute mean difference of 0.52°C 
                         (n=744). The monitored turtles used mainly the continental shelf 
                         area, especially the inner portion (depth lower than 70 meters), 
                         where approximately 65% of the telemetry positions were 
                         registered. During the winter of 2014, almost all turtles moved 
                         north, possibly to avoid colder waters. Only one turtle remained 
                         in high latitudes, but moved offshore and showed a strong 
                         correlation with the northern limit of the subtropical convergence 
                         zone, without transposing the limit towards colder waters. 
                         Overall, registers were close to areas classified as oceanic 
                         fronts, with 27% directly on a frontal area (distance=0) and 42% 
                         less than 10 km from one. We verified strong spatial correlation 
                         between change in movement direction of sea turtles in the oceanic 
                         region and the occurrence of frontal systems. This indicates that 
                         the turtles possibly search for frontal areas due to food 
                         abundance, and for aiding in their displacement.",
